A low-tangling impeller, a low-tangling washing machine and a low-tangling washing method

Abstract

The invention provides a low-tangling impeller comprising an impeller base, a center projection on the impeller base and protruding ribs arranged on the impeller base uniformly and connected to the center projection. Each protruding rib comprises a protruding ridge in the middle and arc-shaped surfaces arranged at the two sides of the protruding ridge to connect the top of the protruding ridge and the upper surface of the impeller base, wherein the arc-shaped surfaces have large bottoms and narrow and shrink gradually upward. The intersecting lines between the arc-shaped surfaces on the two sides of the protruding ridges and the upper surface of the impeller base are curved lines and the curved lines include a plurality of continuous arc lines including inward-concave arc lines, outward-protruding arc lines and inward-concave arc lines arranged from the center of the impeller base to the periphery of the impeller base successively. The end, on the periphery of the impeller base, of each protruding ridge extends gradually from the middle portion to the two sides. The invention also provides a low-tangling washing machine comprising the impeller and a low-tangling washing method. The washing machine is characterized in that the time for a single rotation of the impeller is 0.6-1s and the stop time between two rotations is less than 0.6s. During washing, the protruding ribs with higher outer parts and lower inner parts and the center projection of the impeller can prevent clothes from tangling. Clothes tangling can be further prevented by controlling the rotation and stop time of the impeller.

Description

technical field [0001] The invention relates to a pulsator, a washing machine and a method thereof, in particular to a low-entanglement pulsator, a washing machine and a low-entanglement washing method, belonging to the field of washing machines. Background technique [0002] The pulsator washing machine adopts the scroll type, and the clothes will be turned over continuously during the washing process. During the flipping process, the clothes (especially clothes with slender structures, such as trouser legs, sleeves, etc.) will be entangled with each other. After dehydration, the clothes will be more entangled and difficult to separate, causing troubles to users . [0003] A washing machine pulsator with a patent number of ZL201120489211.8 and a washing machine pulsator with a patent number of ZL201210046667.6 both disclose a structure with protruding blades on the pulsator base, but the pulsator base has a protruding The shape of the blade and the setting of the concave-...

[0003] A washing machine pulsator with a patent number of ZL201120489211.8 and a washing machine pulsator with a patent number of ZL201210046667.6 both disclose a structure with protruding blades on the pulsator base, but the pulsator base has a protruding The shape of the blade and the setting of the concave-convex position on it are of great significance to achieve low winding. The design of the raised blade in the above two patents has a certain effect of reducing winding, but the setting of the impeller structure is relatively simple. In order to better achieve low-entanglement laundry, further improvements to the pulsator are required
